Procurement Notes
Verify the specific suffix OE against the manufacturer's current datasheet to confirm active status and pinout configuration. Ensure the 1.8V supply requirement aligns with the target system design. Confirm that the LVCMOS output voltage levels are compatible with the receiving logic inputs to prevent signal integrity issues or damage.
Selection Notes
Select this component when a precise 11.13 MHz clock source is required with low power consumption capabilities. The integrated enable/disable feature makes it suitable for battery-operated devices or systems requiring dynamic power management. The small footprint allows for high-density PCB layouts where space is constrained.
Part Context
This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages, with the OE suffix indicating specific packaging or operational characteristics defined by the manufacturer for this specific frequency variant.
Replacement Considerations
Direct substitutes include other 11.13 MHz LVCMOS oscillators in 2.0x1.6mm packages from manufacturers such as Epson, NDK, or SiTime. Verify electrical compatibility including supply voltage, output swing, and load capacitance before substitution.
FAQ
Does the 18QHTF21-11.130-OE support spread spectrum modulation?
No, the documentation identifies this part as a standard XO (Crystal Oscillator) without mention of spread spectrum capabilities.
What is the output logic family of this oscillator?
The device uses LVCMOS (Low Voltage Complementary Metal-Oxide-Semiconductor) output logic.
